when a link or switch fails or when STP parameters change.

TACACS+
The TACACS+ protocol exchanges authentication information between a network device
and a centralized database. TACACS+ allows a separate access server to provide
authentication for access to the management console on the Catalyst 2820 series and
Catalyst 1900 series switches. TACACS+ is used in place of a locally configured password.

Configuration and Management Interfaces
The management interface has both a menu console and a web console. Use the
menu-driven system when you have a direct connection to the console port or a Telnet
connection to the switch; use the web console for accessing the switch across the Internet.
There is also a command-line interface (CLI) for entering switch commands directly at the
command prompt.
